SAN ANTONIO - One Alamo Center, a once mostly vacant building after the departure of two large tenants, has been experiencing a resurgence in new leasing activity over the past 18 months.

The latest lease signed for space at 106 S. St Mary's St. is for more than 22,300 sf. It is the new office location for Catto & Catto LLC. The local risk management firm moved a few blocks down from its previous location at 217 East Houston St.

Over the past year and a half, the vacancy rate in One Alamo Center shot up from a low of 39 percent up to its current rate of 88 percent.

The building is owned by Klabzuba Properties, an oil-and-gas investment company that also has a hand in non-energy related ventures.
